which is especially adapted for tipping shoes.

An object of the invention is to provide means for supporting the guidewhereby the same may be shifted laterally to predetermined guidingpositions.

A. "further object of the invention is to provide a guide of the abovecharacter with means whereby the guide may be shifted on .its supportfor varying the set positions of the guide relative to the needle orneedles of the stitching mechanism.

These and other objects will in part be obvious and will in part behereinafter more fully disclosed.

In the drawings, which show by way of illustration, one embodiment ofthe invention:-

the position 'of the lines of It is well known that the tips of shoes'are often ornamented by forming a series of openingstherethroughadjacent the edge of the tip which is' secured to the vamp.-

This edge is secured to the vamp by one or two lines of stitches whichpass through the tip and the vamp on opposite sides of the series ofopenings. This "is known in the art as a tipping operation.

In order that the finished shoe may have the properappearance, it isessential that these lines of stitches should be disposed an equaldistance from the outer edges of the perforations or openings inthe-tip.-

The present invention has to do with'the guide for guiding the tip so asto pro erly position the lines of stitches referre to.

plan view of the pres- 7 This guide is mounted on the support which ismovable so as to shift the guide laterally relative to the needle andthis support is held yieldingly in predetermined positions relative tothe needles. The guide itself is adjustably attached to the support sothat it may be 'adjusted'relative to the set positions of the 7 support.This permits the guide to be not only shifted but adjusted and a properpositioning of the tip for placing the lines of stitching relative tothe'perforationsin the tip and also relative to the edge of the tip sothat the finished article shall be properly constructed.

Referring more in detail to the drawings, I have shown my improvedpresser footl, as applied toza sewing machine having a needle bar 2carrying two needles 3 and 4. There is' alooper -5 whichcooperates withthe needle 3 and a looper 6 which cooperates with the needle 4. Theneedles and the loopers may be operated'in' any welli'k'nown manner.

The presser foot 1 1s carried by a presser bar7. Said presser footcomprisesa shank 8 which is-clamped to the presser bar 7 and a footsection 9 is pivotally secured by a Mounted on the presser foot 9 is anedge guide 11. Said edge guide 11 is fixed to a shank12whiohslides .in agroove13 in the presser foot 9. The edge guideis provided with a section14: which extends underneath the presser foot and the 'inner edge'15 ofthis section 14 isthe guide proper which engagesthe edge of the tip anddirects the same to the needles. The edge guide 11 has an upwardlyextending forked standard 16.

This standard is threaded to engage a threadedadjusting screw 17. Theadjustingv ingly, hold thesupport .in vtwo different set.

Positi n The shaping of the end of'the pin and therecesses is such thata pressure endwise of the support will move said support inthe guide wayand shift the same.

from. one set-position to the other. On the end of thegsupport 18 is acap24 which limits the movement ,of the support if it is moved. beyondthe point where the-pin 23 engages thenotch 21.

In F'gs. 8 and 9 .of, the drawings, Lhave shown a shoe vamp indicated atV1110 which a tipisfattached, indicated at T; This tip is provided witharow. of openings or per-' forations p which extend in a directionparallel with the edge 25 of the tip.T. I have alsoshown inthese figuresa tipesecured to the vamp by two lines of stitching 8 locatedat,one sideof thevopenings or perforations ,and two' lines of stitching 8" located.the otherside of theopenings or perforations p.

In the operation. of .my' device the edgev guide may beset as shown inFig. .6, that is, with. the pin 23 engaging .the notch 20.

.Thisjis one 'set position forthe support .18

p and :when so positioned the vamp. indicated at.V:and the tip indicatedat T in Fig. 6

maybe guided to the presser foot. sothat.

the edge 25 of the tip T willbe in engage- .ment.withthe guiding edge 15.of my-.im-

proved; guide 11;-1 This will position the lines-ofstitching. s so, thatthey will 'bebetween the perforations andthe edge ofIthev tipiand,jof-.z:course, parallel with the edge] of;the".tip., f r I Y PAfter. thisline of .stitching has been formediconneoting thetip to thevamp, then the guide is shifted to the position shown.

incFigL'T This maybe done by. pressing on thecap QLwhich causes the pin23 to rise out of the recess '20 and engage the recess 21.-

When thus positionedthe" line of' stitching siwi'll'ibe formed andthisline of stitching will beiparallel with the edge 25- of the tip;

and located on the opposite sides of the'perforations or openings 79.The presser foot is provided with openings 26 and 27 and the opening% isfor the needle 3 and th'e opening27 for the needle #1. It sometimeshappens that the openings orperforations in the tip of the shoe vary 1slightly in their distance from the edge o f the tip. By turning theadjustingsc rew17, the positionof the guide relative to the sup 7 portmay be changed, and the guide may be shifted from onepredetermined;setpositiorn to another predetermined set positionrelative to the needle openings. Thiswillshift.

the guide laterally from one predetermined set position toanotherpredetermined set; position. By turning the screw 17 the set;positions'of the guide inay-be. varied al; though the setpositionsof theSUPPOBRIB are fixed. Therefore, the distanc betweenj one setpositionandthe other will: ;-remain-;;

the. sameunless the screw 17 istu-rned and if the distance ofthe.perforationsor openings p from the edge ofithe tip bejncjreased. thenby turning the screw-17 'thesetgposi tions may be shifted backfromtheedgeof the tipso thatjhe openings or perforations.

p will be centered between the lines of stiteh mg. g

It also sometimes happensthat the open ings or perforations will vary..-slightly in v size. Under theseconditions thefirst line-ofv stitching 8may be placed -,betwe6ni the -per- .forations or; openings 29and-theedge ofthe tip, thenthe guideshifted-forpositioning th ti forthefline of stitching s andthe screw 17 turned. sufficiently; so as to,center the perforations or openings between .the lines. of stitching.This, injother words, shifts the. set positions of .the guide;so ;tl1at.the distance between the same may be- .either; slightly greater .or,slightly less-as desired 7 although the distance between, the..set-posi-s tions of the support 18 remains fixed. l

Iti'is obvious that, minor changes. jinithe details of construction maybe, made without g departing from. the spirit of, the inventiQI as setforth in theappendedrclaims.
